FIG. 5 is a flowchart illustrating a call connection process through an electronic device according to various embodiments of the present disclosure. Hereinafter, although call reception is mainly described, the present disclosure is not limited thereto and this may be applied to various functions schedule notification, message notification, and alarm.

Referring to FIG. 5, when the electronic device 101 receives a call from the external device 202, the processor 220 may notify a user of the call reception in operation 510. When the first and second parts 110 and 120 are connected (hereinafter referred to as a connection state), the electronic device 101 may notify a user of the call reception through a vibration motor or an external speaker. The vibration motor may be disposed at the third part 130 that is a back portion of the user's neck. The external speaker may be disposed at the external housing of the electronic device 101 and may notify a user whether an event occurs, for example, call reception and message reception, through sound. The external speaker may be formed separately from the sound output module 111 or 121 disposed at the first part 110 or the second part 120. When a user does not plug the sound output module 111 or 121 into the ear, the external speaker may notify a user of an event occurrence such as call reception.

According to various embodiments of the present disclosure, the external speaker may be replaced with a mode for maintaining an output of the sound output module to be more than a specified value. Hereinafter, although it is described that the external speaker is formed separated from the sound output module 111 or 121, the present disclosure is not limited thereto.

When receiving the call as the first and second parts 110 and 120 are separated (hereinafter referred to as a separation state), the processor 220 may notify a user of call reception in a text to speech (TTS) method through a sound output module included in each part. For example, the processor 220 may output sender information by voice through a sound output module as receiving the sender information from the external device 202. In this case, a user may start a call connection through an additional button input or voice input.

According to various embodiments of the present disclosure, in a separation state, as the first and second parts 110 and 120 are connected to each other without an additional user input, the processor 220 may transmit a call reject signal to the external device 202.

In operation 520 to operation 560, an operation of receiving the call in a connection state will be described.

In operation 520, after notifying a user of the call reception, the processor 220 may check whether the first part 110 and the second part 120 are separated in a connection state. A user may separate the first part 110 from the second part 120 and plug the sound output module 111 or 121 (or an ear tip) into the ear to start making the call.

In operation 530, when a user separates the first part 110 from the second part 120, the processor 220 may start making the call through a sound output module and a microphone. According to various embodiments of the present disclosure, by using an acceleration sensor, the processor 220 may be set to allow a sound output module included in each of the first part 110 and the second part 120 to have different outputs.

In operation 540, if the first part 110 and the second part 120 are not separated in a connection state, the processor 220 may check whether an additional specified user input occurs. The user input may be a predetermined type input that a user starts a call without separating the first part 110 and the second part 120. For example, the user input may be a button input, a voice input, and a motion input.

In operation 550, when a specified user input occurs, the processor 220 may connect a call through an external speaker and a microphone (hereinafter referred to as an external speaker mode). A user may freely make a call through an external speaker mode without plugging the sound output module 111 or 121 (or an ear tip). According to various embodiments of the present disclosure, as a call is continued in an external speaker mode, if a user separates the first part 110 from the second part 120, the processor 220 may switch an audio path to a sound output module.

According to various embodiments of the present disclosure, the electronic device 101 may collect movement information or position information of a device by using various sensors (for example, an acceleration sensor, a gyro sensor, GPS, and so on). The processor 220 may automatically activate or deactivate an external speaker mode on the basis of the movement information or the position information). For example, on the basis of a recognition result of an acceleration sensor and GPS, when it is determined that a user is driving or is in a difficult situation and unable to use their hand, the processor 220 may automatically switch to an external speaker mode with respect to call reception in order to provide user's convenience.

In operation 560, when an additional user input does not occur, a received call may be connected through the external device 202. According to various embodiments, when the electronic device 101 receives a call in a separation state, the external device 202 may provide a screen for determining an audio path to a user. For example, when receiving a call, the external device 202 may provide a screen for determining whether to connect a call through a paired device like the electronic device 101 or connect a call through the external device 102 directly. A user may select a desired device and start a call through the selected device.

FIGS. 6A to 6C are views illustrating a call connection method according to various embodiments of the present disclosure. Although a call connection is exemplarily described with FIGS. 6A to 6C, the present disclosure is not limited thereto and this may be applied to functions such as schedule notification, message check, schedule check, and alarm.

Referring to FIG. 6A, a user may wear the electronic device 101 in a connection state and check that a call reception for the linked external device 202 occurs. For example, a user may check a call reception through a vibration motor or an external speaker.

A user may separate the first part 110 from the second part 120 and plug a sound output module (or an ear tip) into the ear to start making the call. A user may select one side call or a both sides call according to the convenience. When the first part 110 and the second part 120 are separated from each other, the processor 220 may allow a call to start by transmitting separation information or call reception request signal to the external device 202. According to various embodiments of the present disclosure, when the first part 110 and the second part 120 are connected again, the processor 220 may end the call.

According to various embodiments of the present disclosure, when a specified outgoing request voice (for example, ‘XXX call’) is inputted through a microphone in a separation state, the processor 220 may transmit a call connection request signal to the external device 202. The external device 202 may generate a call for a specified receiver by the outgoing request voice. In this case, the processor 220 may set an audio path as a sound output module and a microphone.

Referring to FIGS. 6B or 6C, a user may connect a call or check a notification through various kinds of inputs without separating the first part 110 from the second part 120 in a connection state. Referring to FIG. 6B, as recognizing a call reception, a user may start a call connection by pressing a button (for example, a physical button or a touch button) formed at an external portion of the electronic device 101. In this case, the processor 220 may set an audio path as an external speaker and a microphone.

Referring to FIG. 6C, as recognizing a call reception, a user may start a call connection by inputting a predetermined voice. For example, a user may start a call through a voice input such as “receive” or “call” without using their hand. A user may start a call or check a schedule through their voice in an environment in which using their hands freely is difficult, like driving. According to various embodiments of the present disclosure, the electronic device 101 may recognize an operation of a user with an illumination sensor or a proximity sensor and may start a call on the basis of recognition information. For example, when a call reception is notified through a vibration module, as a user provides a specified operation (for example, an action of waving hands in front of the electronic device 101), the electronic device 100 may start a call through an external speaker and a microphone. According to various embodiments of the present disclosure, after starting a call in a connection state, if the first part 110 is separated from the second part 120, the processor 220 may change an audio path to connect a call through a sound output module and a microphone.

FIG. 7 is a view illustrating sound source playback through an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 7, a user may separate parts and listen to a sound source. The sound source may be stored in the electronic device 101 or stored in the linked external device 202. For example, when a sound source is stored in the external device 202, the electronic device 101 may receive an audio signal for sound source from the linked external device 202 and may generate a sound according to the audio signal.

The processor 220 may control sound source playback on the basis of connection or separation information of the first part 110 and the second part 120. For example, when the first part 110 and the second part 120 are separated, the processor 220 may be set to automatically play a sound source. Then, when the first part 110 and the second part 120 are connected, the processor 220 may stop the sound source playback automatically. When the first part 110 and the second part 120 are separated again, the processor 220 may play music again or when the first part 110 and the second part 120 are not separated for a specified time, may turn off the electronic device 101. A user may separate or connect the first part 110 and the second part 120 without an additional manipulation to listen to music conveniently.

According to various embodiments of the present disclosure, the processor 220 may control an adaptive noise cancellation (ANC) function on the basis of connection separation information of the first part 110 and the second part 120. When the first part 110 and the second part 120 are separated, the processor 220 may activate the ANC function and when they are connected, may deactivate the ANC function.

According to various embodiments of the present disclosure, when a call about the external device 202 is received during sound source playback, the processor 220 may stop sound source playback and may provide sender information by a TTS method. The processor 220 may continuously play a sound source after a call is ended.
